I am a mechanical engineer. But I have a lot of interest in astrophysics. I gave some hypothesis in my science fictions about cosmology which i found as some uncommon theories stayed from prior time that i did not know. I mean that my imagination power on cosmology is very strong that is very closer to some scientists theory! I can give many more hypothesis or theory on cosmology. But as i have no educational background on cosmology, can I become an established astrophysicist by reading books, journal or blog ? will any journal publish my idea as i have no educational background? Can anybody suggest me what should I do?

Best answer:
Radio has been about for over 100 years.
Remember that radar and high-frequency radio systems were massively developed during WWII so a lot of the high-sensitivity gear and directional antenna technology was readily available afterwards.

Best answer: Radio has been about for over 100 years.

Remember that radar and high-frequency radio systems were massively developed during WWII so a lot of the high-sensitivity gear and directional antenna technology was readily available afterwards.

Re. general technology back then, as an example the F14 fighter had a targeting system in 1970 that could get an _optical_ lock on an enemy aircraft at a hundred miles in clear conditions;

Radio systems are simple by comparison...

Amateur radio enthusiasts (Radio Hams) have been using the Moon as a radio reflector to get over the horizon on frequencies it's not otherwise possible with since the 50s, using home-built gear. https://en.wikipedia.org/wiki/Earth%E2%8...

Most signal losses occur in in the atmosphere; going straight up through it minimises that - think of satellite TV; the transmitter is 25,000 miles up and using relatively trivial power (eg. 25W for some) but you can pick it up with a tiny dish.

At ground level through dense air, eg. a 25W CB gets you just a few tens of miles, most of the time.

I'm not asking if you believe it is, but could there be a simulation made to replicate our universe, from ity-bity quantum mechanics to every galaxy, star, plants and to us humans with a consciousness. Is it possible?
